Hi all,
I would like to ask your help regarding connecting external modules to telosb. I have found that tiny os offers many possibilities for that as 

ADC,
GPIOs, SPI, UART, I2C

I have never learned anything regarding those. Can someone please let me know if there is any simple
guide on these "interfaces" to show with a primitive example how to start with?

I would like to thank you in advance for your help

Regards
Alex
